Definitions
- the present invention relates to a protected so-called take-out device for hollow glassware, in particular for a hollow glassware molding machine.
- a take-out device for glass bottle molding machines to transfer semifinished products from the pre-mold to the finish mold and/or the finished product (bottle) from the molding machine to a conveyor line, is known, for example, from GB2182297, is normally supported by positioning means movable along three axes, and comprises a support with drive means; a first arm fitted in rotary manner to the support and rotated by the drive means; and a second arm hinged idly at an angle to the first and rotated synchronously with the first arm by a toothed belt-pulley mechanism housed inside the first arm and in turn operated by rotation of the first arm by means of a shaft coaxial with the first-arm rotation member, normally defined by a hollow shaft, but fitted immovably to the support.
- the end of the second arm fitted with the grippers thus keeps the bottles vertical at all times as the first arm rotates about a horizontal axis.
- a device of the type described may be subject to accidental collision with other nearby devices on the molding machine, e.g. pushers, cooling heads, collar arms, etc., which normally operate in strict synchronization with the take-out arm and along frequently interfering paths, but which, for various reasons or improper adjustment, may sometimes drift out of sync and collide with the take-out device.
- other nearby devices on the molding machine e.g. pushers, cooling heads, collar arms, etc.
- the component parts of the take-out device especially the mechanism operating the second arm in sync with the first, and the drive means fitted to the support—may become damaged or at least be knocked out of sync, thus resulting in costly machine stoppages.
- a protected hollow glassware take-out device in particular for a hollow glassware molding machine, as claimed in the attached Claims.
- the device comprises a support equipped with drive means; a first arm fitted in rotary manner to and projecting from the support, and which is connected to and rotated by the drive means with respect to the support; a second arm, equipped with grippers, which is fitted in rotary manner to and projects from the first arm; means for rotating the second arm synchronously with respect to the first, and in turn comprising a shaft, which is coaxial with a rotation member of the first arm, and is secured at one end to the support, and at the opposite end to the first arm; and a kinematic mechanism carried by the first arm and connecting the shaft to a rotation member of the second arm.
- controlled-yielding angular connecting means are interposed between the shaft and the support.
- the rotation member of the first arm is connected to the first arm indirectly via torque transmission means with a predetermined break load.
- the controlled-yielding angular connecting means comprise preloaded elastic means and preload control means comprising: a prismatic first end of the shaft, projecting axially from a through hole in the support, in which the shaft is mounted idly and in fluidtight manner, on the opposite side to the first arm; a lever secured angularly integral with and projecting radially from the first end of the shaft; a threaded rod, a first end of which is screwed transversely through a bushing fitted idly to a fork-shaped free end of the lever; a shoulder element of the support, through which extends a seat perpendicular to the axis of the shaft and through which seat the threaded rod is housed axially; and elastic means, which are fitted to a second end of the threaded rod, opposite the first end and projecting from the shoulder element on the side opposite to the bushing, and are packed between an end head on the second end of the rod and a surface of the shoulder
- any shock to the device is therefore not transmitted to the kinematic mechanism controlling synchronous movement of the second arm, on account of the preloaded elastic means allowing, and also absorbing, a small amount of rotation of the shaft which, being stationary, operates the mechanism as a consequence of the rotation of the first arm.
- the load allowing such rotation can be calibrated accurately and in such a manner it is high enough not to affect normal, i.e. shock-free, operation of the device, by normally keeping the shaft angularly stationary, as a matter of fact secured integrally to the support.
- the torque transmission means with a predetermined break load comprise: an adapter ring bolted frontally to the support and coaxial with the rotation member of the first arm, which comprises a hollow shaft fitted inside the support and rotated by the drive means; a sleeve bolted to and projecting from the first arm, perpendicularly to the laying plane of the first arm, and coaxial with the shaft, which is fitted idly inside the sleeve; and key means connecting the adapter ring angularly integral with the sleeve.
- the sleeve is inserted coaxially inside the hollow shaft, through the adapter ring.
- the shaft operating the kinematic mechanism controlling synchronous operation of the second arm is thus protected by the sleeve, and, in the event of severe shock, stress can be prevented from being transmitted to and damaging the hollow shaft and the drive means fitted to the support, by designing the key means to break in the event of severe shock. In which case, the machine need only be stopped for a very short period to replace the key means and possibly also the adapter ring, if this is deformed.

Description
- The present invention relates to a protected so-called take-out device for hollow glassware, in particular for a hollow glassware molding machine.
- A take-out device for glass bottle molding machines, to transfer semifinished products from the pre-mold to the finish mold and/or the finished product (bottle) from the molding machine to a conveyor line, is known, for example, from GB2182297, is normally supported by positioning means movable along three axes, and comprises a support with drive means; a first arm fitted in rotary manner to the support and rotated by the drive means; and a second arm hinged idly at an angle to the first and rotated synchronously with the first arm by a toothed belt-pulley mechanism housed inside the first arm and in turn operated by rotation of the first arm by means of a shaft coaxial with the first-arm rotation member, normally defined by a hollow shaft, but fitted immovably to the support. The end of the second arm fitted with the grippers thus keeps the bottles vertical at all times as the first arm rotates about a horizontal axis.
- Though satisfactory, a device of the type described may be subject to accidental collision with other nearby devices on the molding machine, e.g. pushers, cooling heads, collar arms, etc., which normally operate in strict synchronization with the take-out arm and along frequently interfering paths, but which, for various reasons or improper adjustment, may sometimes drift out of sync and collide with the take-out device.
- As a result, the component parts of the take-out device—especially the mechanism operating the second arm in sync with the first, and the drive means fitted to the support—may become damaged or at least be knocked out of sync, thus resulting in costly machine stoppages.
- It is an object of the present invention to eliminate the above drawback of the known state of the art by providing a hollow glassware take-out device, in particular for a hollow glassware molding machine, designed to protect its major components from consequences of a collision, and which at the same time is compact, reliable, and easy and relatively cheap to produce.
- According to the present invention, there is provided a protected hollow glassware take-out device, in particular for a hollow glassware molding machine, as claimed in the attached Claims.
- More specifically, the device according to the invention comprises a support equipped with drive means; a first arm fitted in rotary manner to and projecting from the support, and which is connected to and rotated by the drive means with respect to the support; a second arm, equipped with grippers, which is fitted in rotary manner to and projects from the first arm; means for rotating the second arm synchronously with respect to the first, and in turn comprising a shaft, which is coaxial with a rotation member of the first arm, and is secured at one end to the support, and at the opposite end to the first arm; and a kinematic mechanism carried by the first arm and connecting the shaft to a rotation member of the second arm.
- According to the main aspect of the invention, controlled-yielding angular connecting means are interposed between the shaft and the support.
- Also, the rotation member of the first arm is connected to the first arm indirectly via torque transmission means with a predetermined break load.
- According to a further aspect of the invention, the controlled-yielding angular connecting means comprise preloaded elastic means and preload control means comprising: a prismatic first end of the shaft, projecting axially from a through hole in the support, in which the shaft is mounted idly and in fluidtight manner, on the opposite side to the first arm; a lever secured angularly integral with and projecting radially from the first end of the shaft; a threaded rod, a first end of which is screwed transversely through a bushing fitted idly to a fork-shaped free end of the lever; a shoulder element of the support, through which extends a seat perpendicular to the axis of the shaft and through which seat the threaded rod is housed axially; and elastic means, which are fitted to a second end of the threaded rod, opposite the first end and projecting from the shoulder element on the side opposite to the bushing, and are packed between an end head on the second end of the rod and a surface of the shoulder element facing the end head.
- Moreover, axial stop means are provided on the rod, on the opposite side to said surface of the shoulder element to cooperate with the supporting member, on the opposite side to the end head of the rod.
- Any shock to the device is therefore not transmitted to the kinematic mechanism controlling synchronous movement of the second arm, on account of the preloaded elastic means allowing, and also absorbing, a small amount of rotation of the shaft which, being stationary, operates the mechanism as a consequence of the rotation of the first arm. The load allowing such rotation can be calibrated accurately and in such a manner it is high enough not to affect normal, i.e. shock-free, operation of the device, by normally keeping the shaft angularly stationary, as a matter of fact secured integrally to the support.
- According to another aspect of the invention, the torque transmission means with a predetermined break load comprise: an adapter ring bolted frontally to the support and coaxial with the rotation member of the first arm, which comprises a hollow shaft fitted inside the support and rotated by the drive means; a sleeve bolted to and projecting from the first arm, perpendicularly to the laying plane of the first arm, and coaxial with the shaft, which is fitted idly inside the sleeve; and key means connecting the adapter ring angularly integral with the sleeve. The sleeve is inserted coaxially inside the hollow shaft, through the adapter ring.
- The shaft operating the kinematic mechanism controlling synchronous operation of the second arm is thus protected by the sleeve, and, in the event of severe shock, stress can be prevented from being transmitted to and damaging the hollow shaft and the drive means fitted to the support, by designing the key means to break in the event of severe shock. In which case, the machine need only be stopped for a very short period to replace the key means and possibly also the adapter ring, if this is deformed.
- Further features and advantages of the present invention will be apparent from the following description of a preferred, non-limiting embodiment thereof given purely by way of example with reference to the accompanying drawings, in which:
-
FIG. 1 shows an elevation view of a take-out device in accordance with the present invention, for a known hollow glassware molding machine, not shown; -
FIG. 2 shows a section along line II-II of theFIG. 1 device; -
FIG. 3 shows a three-quarter rear isometric view of a main arm of theFIGS. 1 and 2 device; -
FIG. 4 shows a lateral section, as inFIG. 2 and with parts removed for clarity, of the device according to the invention; -
FIG. 5 shows a larger-scale, partly sectioned detail of theFIG. 1 device. - With reference to
FIGS. 1 to 5 ,number 1 indicates a protected take-out device for hollow glassware, e.g. bottles, and in particular for a known molding machine, not shown for the sake of simplicity. -
Device 1, the overall design of which is known, comprises asupport 3 or so-called gearbox, equipped with known drive means 4; a knownfirst arm 5, which is fitted in rotary manner to and projects fromsupport 3, is connected in known manner (not shown for the sake of simplicity) to drivemeans 4, and is rotated bydrive means 4 with respect to support 3 about a horizontal axis A; and asecond arm 6, which is equipped withknown grippers 7, and is fitted in rotary manner to and projects fromfirst arm 5. -
Device 1 also comprises known means, indicated as a whole by 10, for rotatingarm 6 synchronously with respect toarm 5, and which are housed mostly insidearm 5, and in turn comprise a shaft 11 (FIGS. 2 , 3); and akinematic mechanism 14 fitted toarm 5 and connectingshaft 11 to amember 15 for rotatingarm 6 and also fitted toarm 5. -
Shaft 11 is coaxial with a member 12 (FIGS. 2 , 4) for rotatingarm 5, and consisting in a hollow tubular shaft housed idly insidesupport 3 by means ofbearings 13, and connected mechanically in known manner (not shown) to drivemeans 4. - Shaft 11 is connected at one end to support 3, and at the opposite end to
arm 5. More specifically, one end (FIG. 2 ) is bolted to the body ofarm 5, and theopposite end 21 is connected to support 3 as described below. - According to the main aspect of the invention, controlled-yielding angular connecting means 25 are located between
end 21 ofshaft 11 andsupport 3, to mechanically connect the former to the latter. - More specifically, connecting means 25 comprise preloaded elastic means 26; and preload control means indicated as a whole by 27 (
FIG. 5 ). - In the preferred, non-limiting embodiment shown, controlled-yielding angular connecting means 25 comprise
end 21 ofshaft 11, which is prismatic; alever 31 connected angularly integral with, and projecting radially from,end 21 ofshaft 11; a threadedrod 32, afirst end 33 of which is screwed transversely through abushing 34 fitted idly to lever 31; ashoulder element 35 ofsupport 3; andelastic means 26. - More specifically, end 21 projects axially from a through hole 30 (
FIG. 4 ) insupport 3, in which shaft is fitted idly and in fluidtight manner, on the opposite side to arm 5 (FIG. 2 ).Bushing 34 is hinged—so as to rotate freely about its axis, perpendicular torod 32—to a fork-shapedfree end 36 oflever 31, and has a threadedtransverse hole 37 in whichend 33 may screw/unscrew. - A seat 38 (
FIG. 5 ) extends throughshoulder element 35 ofsupport 3 to axially house in a through manner threadedrod 32;seat 38 is normally coaxial with hole 37 (whenbushing 34 is not rotated), and is perpendicular to axis A, which coincides with both the axis of symmetry and rotation ofshaft 11, and the axis of symmetry and rotation ofhollow shaft 12. -
Elastic means 26 are fitted to a smooth (i.e. threadless)second end 40 of threadedrod 32,opposite end 33 and projecting fromshoulder element 35, on the opposite side to bushing 34, and are packed between aprismatic end head 41 onend 40 ofrod 32, and a surface 44 (FIG. 5 ) ofshoulder element 35 facinghead 41. - In the example shown,
elastic means 26 comprise a pack of disk springs packed tightly betweensurface 44 andend head 41 onend 40 ofrod 32; andsurface 44 is spherical and cooperates with the pack of disk springs definingelastic means 26 with the interposition of awasher 45, which has a spherical surface mating and cooperating with that ofshoulder element 35, and is fitted in sliding manner to thesmooth end 40 of threadedrod 32. - To complete the
mechanism connecting rod 32 to supportingmember 35,rod 32 is fitted with axial stop means located on the opposite side tosurface 44 and comprising awasher 50, which also has aspherical surface 52, but facing the opposite way tosurface 44; and a threadedbushing 51 screwed to threadedrod 32 and having a spherical surface which cooperates withsurface 52 to lockwasher 50 axially. - Subjected to the thrust of elastic means 26 preloaded between
head 41 andsurface 44 by appropriately screwingrod 32 insidebush 34, washer 50 cooperates withshoulder element 35 ofsupport 3, on the opposite side tohead 41 ofrod 32, to preventelastic means 26 from rotatinglever 31, together withshaft 11, anticlockwise (FIG. 5 ). This “zero” position corresponds to the normal stationary operating position ofshaft 11, and can be fine-adjusted by screwing orunscrewing bushing 51 onrod 32. - To avoid kickback in use,
rod 32 is preferably fitted, close toend 33, with a flange 55 (FIG. 5 ) screwed torod 32 and facing awasher 56 adjacent to asurface 57 of fork-shaped end 36 oflever 31; and secondelastic means 58, also comprising a tight pack of disk springs, are packed tightly betweenflange 55 and washer to presswasher 56 againstsurface 57, which is curved with a radius of curvature centred at an axis B of rotation ofbushing 34. - The pack of
elastic means 58 serves to take up any slack betweensurface 57 oflever 31 and the surface ofwasher 56, by keeping the surface ofwasher 56 pressed at all times againstsurface 57. This ensures immediate response when adjusting the angular position ofarm 5 with respect to support 3, byunscrewing screw 62 and rotatinglever 31 onprismatic end 21 ofshaft 11.Surface 57 being curved, the pack ofsprings 58 is compressed uniformly, so the operator need only apply constant force (neither increasing nor decreasing) to centre the position of the arm. - At the opposite end to fork-shaped
end 36,lever 31 has aU-shaped end 60 fitted toprismatic end 21 ofshaft 11 and locked to it byscrew 62 fitted transversely through U-shaped end 60 (FIG. 5 ). - According to a further aspect of the invention, the rotation member or
hollow shaft 12 ofarm 5 is connected toarm 5 indirectly via torque transmission means 70 (FIG. 2 ) with a predetermined break load. - More specifically, means 70 comprise an
adapter ring 71 bolted to the front of the support and coaxial with hollow shaft 12 (FIG. 4 ); asleeve 72 bolted to and projecting fromarm 5, perpendicularly to the plane ofarm 5, and coaxial withshaft 11, which is fitted idly insidesleeve 72 by means of abearing 73; and key means 74, 75 (FIGS. 3 , 4) connecting the front ofadapter ring 71 angularly integral withsleeve 72. - Sleeve 72 (
FIG. 2 ) is inserted coaxially insidehollow shaft 12 throughadapter ring 71, and is locked axially and coaxially at the front againstadapter ring 71 by at least onescrew 78 parallel tohollow shaft 12 and fitted through alug 79 onsleeve 72, close to one of thekey slots 75 formed on the front of amounting flange 80 ofsleeve 72. Conversely, the front ofadapter ring 71 has respective projecting, integral keys 74 (FIG. 4 ) formed in diametrically opposite positions, and only one of which is shown in the drawing. - In actual use, elastic means 26
hold washer 50 resting againstelement 35 renderingintegral shaft 11 to support 3 by means oflever 31. So, whenarm 5 is rotated by rotatinghollow shaft 12,shaft 11 remains stationary, andmechanism 14 insidearm 5 rotatesarm 6 synchronously by rotatingshaft 15. - In the event of shock to
arm 6, shaft 15 (and, therefore, mechanism 14) is subjected to a torque C (shown by the arrow inFIG. 1 ), which corresponds to torsional stress T (indicated by the arrow) onshaft 11, and, vialever 31, to axial stress S (indicated by the arrow inFIG. 1 ) onrod 32. - This stress further compresses the already preloaded
elastic means 26, so thatrod 32 moves towardsarm 5; washer 50 detached fromshoulder element 35; bushing 34 rotates about its axis B with respect to fork-shaped end 36; andlever 31, together withshaft 11, is rotated by and in the same direction as torsion T, which is damped by the resistance ofelastic means 26, without any kickback being exerted onmechanism 14 or, worse still, being transmitted toshaft 12. Once the effect of the shock dies down, elastic means 26 restore the original situation. Any excessive angular movement ofshaft 11 is prevented bycurved slots 90 formed onend 60 oflever 31 and engaged bypins 91 integral withsupport 3. - In the event of shock to
arm 5, the torque exerted onshaft 11 is absorbed byelastic means 26 in the same way as described above. Moreover, if stress is severe enough to damageshaft 12, kinematic mechanism 14 (this is the weakest and in fact the first to fail), and the mechanism drive gears fitted to support 3, it is prevented from being transmitted toshaft 12 bykeys 74 breaking and angularly disconnectingsleeve 72 integral witharm 5, andadapter ring 71 integral withshaft 12. Operation ofdevice 1 is restored quickly by replacingring 71.
